VII.2.3.11 Spreadsheet “LamLoadResponse_A”
This spreadsheet calculates laminate load response for a laminate defined in the current composite
dataBase, and a loading also defined in the current dataBase. The buttons allow to select:
- An existing laminate (in the active dataBase),
- An existing load (in the active dataBase),
- The orientation wrt which laminate properties are calculated,
- Whether plies result outputs are requested at bottom, mid or upper surface of each layer,
- Whether the ply stresses and strains are restituted in coordinate system related to laminate
axes or in ply axes,
- The last button gives the rotation angle wrt laminate axes of the restitution coordinate
system. (This button is used only if the previous button is set to “YES”.
The spreadsheet makes use of several functions defined in “calcLamLoadResponse” VBA module. These
methods calculate laminate global stress/strain state, ply stresses and strains, and failure indices,
reserve factors or equivalent stresses.
